Description
The present invention relates to a kind of two sections shaping surgery technology assistors that are positioned at, for example, swing type connected device between the artificial limb, has adjustable inherent hinge-stability of foundation, it is made of a plane motion linkwork, this hinge comprises four articulated elements at least and presents by translation and the synthetic multiaxis heart of rotative component swing characteristic, has at least the swing of an articulated elements to be subjected to the restriction of one first swivel stop at least one swaying direction, and articulated elements can be made one or paired.
Such swing type adapter for example can be used for artificial limb knee-joint.Its flexural property is by by translation and the synthetic multiaxis heart of rotative component representation of athletic, and this motion is equivalent to two curves rolls relatively, and its contact point has constituted the moment center of rotation of motion.Every this so-called polar all is located on a section of the artificial limb that connected together by multiaxis heart swing type adapter.This polycentric knee joint can provide according to the different designs of its basic geometry than the single shaft heart or the bigger advantage of mono-axial knee joint structure, the advantage during except seat, mainly be that stand the stage (contact to earth from heel and lift until toe) when walking has very big advantage.
Single shaft heart artificial limb knee-joint, the retrodisplacement that static stability when standing only relies on the loaded line rear portion guarantees, owing to the walking that acts on of heel power begins understand unstability because of the change of loading direction in the upright stage, stretch hip moment and fall because of knee bends preventing so the amputee must produce one.The size of moving after the size of this moment and the knee joint is relevant.Amputee's health firmly can by-move after reducing and alleviate, but owing to the degree of stability loss that therefore has and must take indemnifying measure, for example to install a location additional and move and decide element, its structure can be a mechanical brake or hydraulic damper.
Compare with single shaft heart joint, multiaxis heart artificial limb knee-joint when its stretch the position moment center of rotation position when higher relatively, it is not only under standing state, and all have outstanding intrinsic stability in the beginning in the upright stage of walking that the effect of heel power is arranged, need not to stretch hip moment on the position and also can keep stable stretching.Another advantage is exactly can be by suitable design, at the end reach natural gait in the stage of standing and carry out the transition to subsequently recovery phase in phase, for this reason, to produce a knee bend by front foot load, move the kneed artificial limb of the formula single shaft heart after the employing, common amputee can not satisfy above-mentioned requirements, because almost can not produce the necessary hip moment of stretching enduringly.Yet have above-mentioned polycentric knee joint designs artificial limb and crooked but only needs much smaller stretch hip moment, common amputee can have no to make this moment tiredly.But this advantage had only when the moment of stretching the position, center of rotation can be adjusted to the optimum position and could realize.
Have the advantage of multiaxis heart joint of artificial limb of above-mentioned functions feature also corresponding usually a shortcoming: the intrinsic stability of giving prominence to its straight configuration under promptly can be lost under minimum angle of bend.Therefore also do not design a kind of artificial leg structure up to now, can make the amputee except have wear also can increase the above-mentioned advantage that multiaxis heart joint of artificial limb can reach another kind of may, promptly make it under the effect of heel load, produce a kind of elastic shock attenuation and/or buffered knee bend in the initially stage of standing of walking in the mode that is similar to natural gait, do not produce simultaneously the loss of stability, shock-absorbing effectively so on the one hand, can further improve gait and human body distribute power again on the other hand, make that the gravity center of human body's move both vertically that balance coordination ground carries out in the whole phase process of standing.
Task of the present invention is the function of expansion multiaxis heart swing type adapter.
The solution of above-mentioned task is to have at least the length of an articulated elements can change under the effect of external force.This length Change Example be as can finishing by following manner, be about to pin joint that two articulated elements connect together can be under the effect of load along one or/and the direction of another articulated elements move.
Sometimes can also the opposite drag devices of direction, for example a kind of device, buffer or analog that produces mechanical friction be set for above-mentioned length changes.
When the length change is elastic type at least on an articulated elements, be very favourable.The change of length must overcome the effect of a restoring force in this structure.Spring rubber bullet device or pneumatic means etc. can be set for this reason.In principle also can be with leaf spring as adjustable length articulated elements.
In design example of the present invention, the mode that distance by two adjacent pin joints can shorten under the load effect makes the lower hinge part produce a swing to curved side relevant with load with respect to upper articulation, at the same time, moment center of rotation along a straight line that tilts towards the curved side away from this swing type adapter, above-mentioned straight line neat mutually with the longitudinal axis that is limited to each articulated elements on the extreme position by swivel stop (one-tenth delegation).
This additional movement relevant with load can improve adjustable intrinsic hinge-stability of foundation, and, structure of the present invention changes because doing simple drive technology, thereby can otherwise influence adjustable inherent hinge-base fixed: the general characteristic of the swing type adapter of being invented is, under an external load function, can produce a limited controllable additional movement in a predetermined direction, and adjustable inherent hinge-stability of foundation is on purpose increased merely according to different structural designs, remain unchanged or reduce, perhaps with this effect qualitative with carry out certain combination relevant quantitatively with additional movement.
Hereinafter, promptly relate to a kind of very favourable application of the swing type adapter of being invented as long as the part relevant with knee joint all relates to an example.
The swing type adapter of being invented uses as knee joint a kind of possibility is provided for the first time, makes knee no any advantage of restrictedly utilizing above-mentioned known multiaxis heart artificial limb knee-joint in the stage of initially standing of walking under the effect of heel power.Therefore the function of the artificial limb knee-joint of being invented has exceeded the well-known single shaft excess of the heart example with " elasticity knee joint " significantly.
In order to regulate the stability in joint, preferably make first swivel stop adjustable.Adjust the maximum possible degree of freedom of stability of joint and only after having taked addition thereto, could realize, for example manually change the length of an articulated elements.
The improvement of the stability of carrying swing type adapter has significant meaning for kneed application, and first swivel stop promptly is set between the articulated elements of two rigid structures, and one of these two articulated elements preferably are made of the top connector.
When the swing type adapter of being invented is used as knee joint, first section of its plastic surgery's assistor is the artificial leg upper limb, second section is the artificial leg lower limb, four rod member hinges system constitutes knee joint, kneed two articulated elements that are fixed together with upper limb (stretching the side male part), and articulated elements (curved side male part) footpath pin joint that is positioned at the rear portion interconnects, according to the present invention, the male part of its curved side preferably one can be under the load effect elasticity change the articulated elements of length.
In addition, the pin joint that connects curved side male part and lower hinge part is installed adjustablely and can be fixed on the collection position of requirement preferably vertical on the articulated elements of bottom.
Further feature of the present invention is seen dependent claims, and the advantage of comparative examples to invention is further described.
The contrast sketch map is illustrated the present invention below, and describes a special example in detail.

Fig. 9 represents the side-looking enlarged drawing of structure shown in Figure 7, and has marked hunting range therein;
Figure 10 represents that structure shown in Figure 9 is in case of bending.
Fig. 1 schematically shows one and is in the swing type adapter that stretches the position, and it is made up of a cover plane motion hinged system, and this catenary system has four articulated elements 5,6,7,8, and they are linked together by four pin joint A, B, C, D.The connector 6a that upper articulation spare 6 draws by a signal can be connected with the epimere of shaping technique assistor.Equally, lower hinge part 8 can be connected with the hypomere of shaping technique assistor by its a connector 8a.In Fig. 1, the articulated elements 5 that is positioned at the right is that the male part that direction is arranged is stretched on an edge, and it is positioned at the opposite of the articulated elements that is in the curved side 7 on the left side.The position of stretching of this oscillating motion is located by block 9, and this block defines upper articulation spare 6 and stretches the maximum of angle u between the side male part 5 in illustrated embodiment.
Above-mentioned is a kind of known swing type adapter, and the distance between its adjacent pin joint all can not change, and its flexural property is used by what heavy line drew and stretched position (α
0) set out with three grade bending (α 1, the αs of bottom articulated elements with respect to static upper articulation spare
2, α
3) expression.This flexural property is made up of translational component and rotational component, therefore synthesized a kind of multiaxis heart motion, this motion is intersected the limit track with the pole curve DK(of representative on the immobilized upper articulation spare in the drawings) dotted line represent, this curve connects together all and each bending position center of rotation of corresponding moment, in illustrated example, it is corresponding to the moment center of rotation P that stretches the position.Be positioned at the peak in joint.
What Fig. 2 represented is swing type adapter of the present invention.Different with example shown in Figure 1 is, the articulated elements that is arranged in the curved side 7 herein is subjected to the effect of an outside elastic pressure (figure does not draw in detail) can change its length, and its underpart pin joint C can move towards the direction that upper articulation is put D under the effect of stage clip 22.From no-load initial position (β
0=α
0) setting out has marked two shift positions relevant with load of pin joint C, it can cause angle beta of lower hinge part 8 swings
1Or β
2, and male part 7 usefulness of curved side are swung around upper articulation point D.Compare with Fig. 1, this place is a kind of additional movement relevant with load, and this motion is represented with angle separately in Fig. 2, so as can be seen, is remained unchanged by the angle position between the block 9 determined rigidity articulated elements 5,6.
The effect of the additional movement relevant with load is to make the lower member of swing type device produce curvature movement with respect to immobilized upper component, and the wink center of rotation P that is determined by the extending line intersection point of two male parts 5,7 is simultaneously also moving.This moment moment center of rotation P move relevant and the formation straight line with the bending position of lower member, this straight line is represented the extended line of each male part 5,7 longitudinal axis, the extreme position that is limited by block 9 of male part remains unchanged.In example shown in Figure 2, all moment center of rotation P '
0, P '
1And P '
2All be positioned on the extended line of the male part of representing with chain-dotted line 5, and in selected example, moment center of rotation P ' along with the increase of angle of bend β away from the joint.This effect has great meaning to solution of the present invention.
Embodiment shown in Figure 3 and the difference of Fig. 2 only are that pin joint C is not the direction towards pin joint D, but overcome the power of a unillustrated spring or analog and move under the effect of load towards the direction of pin joint B.The mobile of pin joint C is limited in the slit 17, therefore also can be similar with Fig. 2, and make lower hinge part 8 swing relevant with load take place and moment center of rotation P is moved.
Example shown in Figure 4 and Fig. 2's is similar, and just block 9 is used for the swing of limit flexion side articulated elements 7 with respect to upper articulation spare 6.Moving of moment center of rotation P ' is relevant with respect to the bending position β of immobilized upper component with lower member, and on the mobile extended line that occurs in the male part 7 that chain-dotted line represents.In addition, also be provided with vertical block 30, it defines the maximum that elasticity shortens or pin joint C moves with respect to pin joint D of curved side male part 7.
Fig. 5 has shown a kind of swing type adapter as Fig. 2, and it has embodied obvious advantage of the present invention, has promptly increased the additional movement relevant with load again, the bend angles alpha in requiring basic exercise on the basic exercise basis of known and load-independent
1=20 °, pairing moment center of rotation P
1Abut against the top in joint and be positioned at stretch side the limit before the time, for β
1=20 ° the angle of bend relevant with load, moment center of rotation P '
1To be positioned at the top in joint far away, and be in after its curved side limit.Clearer and more definite signal can be referring to Fig. 6, and the basic geometry of swing type adapter wherein and Fig. 5's is proportional fully.Under the effect of the load F that points to heel, stretching the knee stretching strength square M that produces on the position
0=F * d
0In the known configurations improved more than the twice owing to only having utilized when the knee bends, reached M '=F * d with additional movement load-independent
1'.Only utilized when knee bends under the situation of in the known configurations and basic exercise load-independent, will produce the moment that great direction is opposite, caused and can not pass through muscle balance, this just will inevitably cause amputee's limping in practice or fall down.
Fig. 7 to Figure 10 is the special embodiment that swing type adapter of the present invention is used for artificial limb knee-joint.
Describe the structure of Fig. 7 below in detail to artificial limb shown in Figure 10.
Artificial leg lower limb 2 are made of a grip assembly, and pseudopod 3 is being fixed in its lower end.Artificial leg upper limb 4 can be made with the thigh stump or cut the shape that the knee joint stump adapts.
The lower end of two male parts 5,7 respectively is hinged on the lower hinge part 8 by a pendulous device 16,8 upper ends that are fixed on assembly 12 with clamping mode of articulated elements.The pendulous device 16 of the lower end swing of curved side male part 7 is led by the slit 17 that is positioned on the lower hinge part 8, and can be fixed on the desirable position in slit 17 inside.Therefore can be by the bent side male part 7 of the length of manual change lower hinge part 8 with respect to the position of stretching downside male part 5, thus height and the kneed comprehensive stability of moment center of rotation P can be adjusted to optimum.
Curved side male part 7 comprises a bearing pin 18, its lower end is installed in the back-up block 19 on the pendulous device 16 guiding longitudinally a swing, twisting a nut 20 in the lower end of bearing pin 18, that it can determine male part 7 under the state that oscillating motion does not stress this male part of effective fundamental length also can be made is adjustable-for example by use another (to twisting) pile female-may with what increase a kind of adjusting.
The end of bearing pin 18 is also being twisted a nut 21, and it can be regulated for the pin-and-hole that bearing pin 18 is hinged on the top pendulous device 14, and has formed a bearing of stage clip, and the lower end of stage clip 22 then withstands on the supporting seat 19.Nut 21 pretightning force that can regulate stage clip 22 by rotation top.
When knee joint 1 for example is subjected to time spent of doing of artificial leg user body weight, stage clip 22 is compacted, and bearing pin 18 moves relative to back-up block 19 simultaneously.Therefore the distance between two pendulous devices 14,16 shortens and causes therefrom the shortening of the effective length of the curved side male part 7 that the motion to the joint plays an important role.Consequently moment center of rotation the position change.
Curved side male part 7 also can be made leaf spring shape, and it can produce very big bending under the load effect, and this can shorten two distances between the swing point 14 and 16 equally.
When artificial limb is in the straight configuration (see figure 9) and still has prosthetic user's a action of gravity under this state, then it is important to make moment center of rotation P to be positioned at the rear of load position, only in this way just can avoid this many bars hinge to tie up to following its basic exercise curve under the influence of load and do oscillating motion.Because the relative position at straight configuration lower hinge 5,6 is determined by first block 9, so because of the shortening of the effective length of articulated elements 7 can make moment center of rotation P produce a displacement, this displacement takes place along the extended line of anterior articulated elements 5 or the extended line of the connecting line between two pin joint 14,16.In order to realize high as far as possible degree of stability, importantly to make this line be positioned at the rear of load F position all the time.
Comfortable for the artificial leg that has the polycentric knee joint is used, very important to make exactly moment center of rotation can be as shown in figure 10 along with the increase at knee bends angle near the knee position, in the time of particularly or on the seat in recovery phase.
